ACETYLENE-L-AMP.

Specification of Letters Patent.

Patented Dec. 28, 1915.

Application filed March 5, 1915. Serial No. 12,295.

To all whom it may concern:

Be it known that I, Acorn L. HANsnN, a citizen of the United States and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Acetylene- Lamps, of which the following is a specification.

My invention relates to acetylene lamps, and particularly to miners lamps- Lamps of this class usually comprise a water container, a carbid cup and a' burner and reflector, and one of the important objects of my invention is to provide such compact and otherwise improved arrangement of these parts as will particularly adapt the lamp for miners and will cause it to more efliciently direct the light to the work.

Another feature of my invention is particularly adaptable where the burner is as sociated with the carbid cup and such cup is detachable from the water container in order to be replaced when the carbid becomesexhausted, the feature involving improved valve mechanism for automatically connecting the water supply with the carbid when the carbid cup is attached to the water container, and for automatically closing the cup when the cup is removed in order that the final gas supply from said cup can be utilized for illuminating purposes while a cup with a fresh charge is secured to the water container.

Another object is to provide a strong and compact carbid cup structure and improved arrangement of a combined burner, reflector and gas cleaning structure in connection therewith.

The invention also involves other features of construction and arrangement all of which assist in producing simplicity and compactness, and ready accessibility to all parts for inspection cleaning and repairs.

On the accompanying drawing I have shown a lamp embodying the various features of the invention and Figure 1 is a side elevational view of a lamp showing it in place on a miners cap, Fig. 2 is a top view of the lamp, Fig. 3 is a sectional View on plane 83, Fig. 2, and Fig. 4c is a secengagement being in the usual well known manner. Extending vertically through the water container between the bottom frame 1 and the top wall thereof is the vertical water duct 14: having the inlet slit 15. Secured to the under side of the wall 10 opposite the lower end of the duct 14 is the coupling member 16 whose reduced end 17 extends into the duct 14: through the opening 18 in the wall 10. Through the coupling member extends the axial passage- Way 19 which at its inner end is flared to form the conical valve seat 20 for the valve stem 21 which extends through the water duct 14. At it upper end the water duct is internally threaded to receive the threaded upper end 22 of the stem so that turning of the stem one way or the other will cause its conical end 6 to open or close the passageway 19 to the duct 14: and the water container. A lever 28 is secured to the upper end of the stem and has a spring latch 24 for cooperating with the detent projections 25 formed in the upper wall of the Water container. The upper wall of the water container has also the water supply inlet 26 for which a plug 27 i provided.

Describing now the carbid container G, the body 28 of this container is cup-shaped with a convex bottom and its outer edge section 29 is threaded for receiving the cover structure 30. Extending axially through the cup 28 from the bottom thereof is a valve barrel 31 whose outer end provides the threaded socket 32 for receiving the threaded coupling member or plug 16 which extends from the water container, this coupling engagement serving to secure the carbid container to the wall 10 and when thus tension 42 abuts against the end 43.

secured the convex bottom of the cup fits into the dome 10 in very compact arrangement, and when the lamp is hung on the cap frame F the water container will be dis posed horizontally and the axis of the carbid container will be at an angle with the horizontal, and such axis will be substantially parallel with the vizor v of the cap.

The inner end of the barrel 31 forms the valve chamber 33 for the check valve 34, and the wall 35 between the valve chamber and the socket 32 has the inlet opening 36 whose inner edge is beveled to form the seat 37 for the valve 34. A spring 38 encircling the valve stem 39 between the valve and the removable cap 40 for the barrel tends to hold the valve against its seat to close the inlet opening, the barrel having longitudinal water passageways or slits 41 connecting the valve chamber with the interior of the carbid cup. An extension 42 on the valve projects through inlet opening 36 and is of less cross section area than said opening. The outer end 43 of the coupling member or plug 16 is of reduced diameter and forms an abutm'ent for the projection 42 when the carbid container is secured to the water container. When the carbid container is removed the spring 33 will cause the valve to close the water inlet opening 36, but when the container is screwed to the member 16 the valve projection will encounter the end 43 and the valve will be shifted away from its seat to efiect connection of passageway 19 with the valve chamber and the carbid cup, the end 43 being provided with radial slits or passageways 44 for the passage of water when the ex- When the two containers are coupled together and the valve stem 21 is turned to open passageway 19 to the water container, water will flow through this passageway and passageway 36 and through slits 41 into the carbid cup and gas will be generated. Upon uncoupling of the containers the spring 38 will cause valve 34 to close the water inlet 36 to seal the carbid container a ainst escape of gas through such inlet. Fingers 45 are projected from the valve through the passageways 41 and when the valve is shifted during coupling of the containers these fingers will clean the passageways of any accumulations of carbid and the valve extension 42 moving in the inlet passageway 36 will clean this passageway of any accu Inulations in order that water may then freely flow from the water container to the carbid container.

The cover structure 30 already referred to is deflected inwardly or concaved and has the threaded flange 30 for engaging the threaded end of the carbid cup, a washer 46 being inserted between the cover and the cup to insure sealing fit. Extending axially and secured to the cover is the block 47 having the threaded socket 48 for receiving the threaded inner end of the burner frame 49 which extends axially through and is secured to the concave reflector 50. The reflector with the deflected part of the cover 30 forms a chamber 51 interposed between the carbid cup and the burner frame, the cover being provided with small gas outlets 52 and the burner frame having the radial inlets 53 to its central passage 54 which passage communicates with the tip 55 seated in the outer end of the burner frame. To insure sealing a suitable washer 56 is interposed between the reflector and the cover 30.

In order to filter and clean the gas be causing the rays of light to be projected onto the work in front of the miner. The arrangement is such that the lamp can be readily and accurately controlled and kept in the best working condition. When the carbid in one container is almost exhausted, another container can be substituted, and such substitution can be made by the light of the removed container. The valve mechanism which is automatically controlled upon coupling of the carbid container to the water container keeps the water passages clear. The generated gas before reaching the burner is filtered and the heavier particles will fall to the bottom of chamber 51 to be expelled when the reflector is removed from the cover 30. To facilitate removal of the cover from the reflector structure when it is desired to refill the carbid cup radial projections 59 are provided on the flange 30 of the cover, these projections, as shown, beingin the form of loops in a band 60. In order to strengthen the cup its convex endmay be corrugated as indicated at 61. bid in the cup is apt to become caked it is customary for the miner to tap the cup against his heel or a wall. However, the corrugations will protect the thin sheet metal against bending and indenting. The corrugations also facilitate coupling and uncoupling of the carbid container and wa-' ter container. In order to guide the carbid As the carcup into coupling position, guide ears 62 are extended downwardly from the sides of the water container.

I do not of course desire to be limited to the precise construction and arrangement shown and described, as changes and modifications are no doubt possible which would still come within the scope of the invention.
